Do your exhaust fans have sealed motors... that is, are they approved for use in areas where they will exhaust FLAMMABLE air? If not, you may be asking for trouble. Also, what means will you have to dry the compressed air?

Well…. The sales pitch on this fan says it is “completely sealed with thermo protection.” Does it have a stamp on it that says “safe for dangerous atmospheres,” no it does not. I believe it is because of the blades. They are galvanized. Not aluminum or plastic. Yet the loovers are plastic.

As for the drier, I always ASSumed I would have to buy one of those expensive water separator and drier combo things.

And on a side note: I got home Friday but my dad killed my weekend with a C10 454 swap…. We swapped out the 305/th350 and dropped in a 454/th305 (2nd th350 was “rebuilt”). Turns out the 2nd th350 is $H(T and did not move the truck forward. So today we put the original th350 back in the truck….. So, nothing was done on the booth……

Very nice job. I highly recommend a refrigerated air dryer if your budget can swing it. Before i got mine I put an old external engine oil cooler in line just after the compressor followed by one of the cheap water seperators from harbor freight and then had a box fan blowing air over it. It was ghetto but I was suprised how much moisture it condensed.

Nathon, did you use explosion proof fixtures and wiring methods. In my 50+ years in the electrical trade I have seen several home built spray booths go BOOM. The scariest was a guy that had cordoned off half his garage with plastic sheeting. One evening after he had just laid the base coat he went in to get something to drink. The explosion knocked him and his wife down and the house off of its foundation and totally destroyed their son's bedroom (it had a common wall with the garage). By His grace the son was out riding his bike with friends at the time it blew. Just curious.

I'm just finishing up a 40' x 60' shop with a two post lift, a bathroom, a craft room for my wife, lots of overhead storage and a lockable tool crib. I am going to build a metal framework that I can use outside and cover it tightly with plastic. I helped a friend years ago build one and it worked great. It was 12' wide, 10' tall and 24' long. He used a former heater squirrel cage fan that was cleaned up then boxed up with filters sealed to the box. He bought a ceiling fan speed control to regulate the speed.

Good luck on your project. I hope to do my own painting too, once I get the shop completed.

Sucks I have to bring this up nopw. but if you are going to be spraying water around, you should have have a concrete or concrete block knee wall installed at the bottom about 6-12 inches tall before the bottom plate, as it in now the water will rot out the bottom plate being as how its sitting right on the concrete. other than that it looks nice , you should post this up over at The Garage Gazette - Index lots of tips and tricks for garages over there.
